KGN -12 fixed metal-clad switchgear(short for switchgear as below) applies to 3.6~12KV,
3 phase AC 50/60Hz network for receiving and distributing power energy and also for control, monitor and protection.
It can be used in s ingle busbar, single busbar section system.
It is manufactured inaccordance with IEC62271-200 & GB3906 3~35KV AC Metal Enclosed Switchgear, DL404 Order Specification for Indoor AC HV Switchgear and so on.
It has reliable prevention function against false operation.
- Q: I have worked there as an electrical engineer but in design for a consultant. I would like to know what are the major things to account for (DB's, wires and cables, ducts, conduits.) and how to estimate them for a typical 6000sq.ft 2 floor villa
- If you have the design drawings, you simply have to make a material take-off list. The main drawings are: General Layout Grounding Layout Electrical Equipment Layout / Schematic Riser Diagram (Fire Alarm) Lighting Layout At the very least, you need to have the General Layout drawings (to know how many rooms you've got) and you need to know the electrical levels since some houses might require 380/480 3-phase for elevators and large electrical equipment. Working room by room, you will estimate cable and conduit lengths, the number and specifications of the DBs, number of lights, outlets, switches, buzzers, intercoms, smoke detectors.
- Q: I have a piece of electrical equipment at a voltage potential of 277VAC to ground. Due to hardware problems I have an air gap of 3/8 from ground to 277VAC when it used to be one inch. Please advise if I am safe to leave it that way or should I add insulation.
- That is ok with respect to any possible arc. But there may be other reasons to add insulation. Safety for example. If it's easy to add the insulation, do it. .
- Q: i would like to know more about the functions of this room. What is the role of this room in electrical distribution in a building? What i know,an electrical components need to get through this room such as for lighting+ac, power socket, and essential power.
- A riser room is where the electrical distribution equipment ( Switchgears and Panels) that supplies the electrical systems of the building is located. Electrical conduits that feed the various equipment, A/C units and sub panels and fire pumps originate here.
- Q: HI I need to know if anyone knows the MN electrical code for how many can lights I am allowed on one circuit using 14-2 with 15amp. also I would like to put some in my soffit outside, any type of can required for this? Thanks.
- Just keep the total load less than 80% of the circuit and you should be fine, even Dave Jacobson would not have a problem with that, he is a fun inspector to deal with, if you are borderline will depend on the inspector, if you are over it will not fly. In the 2008 code there is this nice little deal about all electrical equipment installed outdoors, has to be rated either for damp, or wet locations, even gfci outlets in an in use cover, and in a house have to be of the tamper resistant type . If you watch those things, even good old Dave won't have a problem with it, but I bet he still looks at every breaker in your panel, the label I mean Good luck.
- Q: I know that it would destroy active electrical equipment but if the device had no electricity going through it at the time could it be affected?
- nan
- Q: i dont understand this, every surge protector claims to protect phone lines from surges but why?
- Because DLS and phone lines operate on voltages and currents and are susceptible to lags/spikes. GL
- Q: I recently came across an article that many Jews are now reevaluating whether electricity really is tantamount to lighting a fire, a forbidden act on the Jewish Sabbath, due to advances in our understanding of electricity through modern science. Is anyone aware of changing opinions on the use of electricity on the Jewish Sabbath? Are some Orthodox groups really changing their position?
- Please read the verses up to and past Jeremiah 8:8. Read all the versions. KJV is s poor translation. What do you think a lying pen of the scribe that works falsehoods is? The people did not know the true law of God because of them. Think about this for awhile and read the first few chapters of Levitcus to a child and see what they think. Follow God, not the lying pen of the scribes that changed scripture! Edit: I said KJV was bad translation did I not? I am not a Jew either. I just try to use common sense and follow what Father and Yeshua (Jesus) said. Can you not tell the things they did not say? BTW: Why not be concerned about Father's Law over Jewish law? I also believe in and keep the seventhday sabbath and do not and will not attend any church. Do you follow man or do you follow Father in Heaven? That is the question we must ask. I dare you to study Jere. 8:8 with an open mind and heart. If not, you just don't care to follow the true Father in Heaven. That is up to you. Look at Annt: This is the perfect example of man made law. You have got to be kidding. It is total non-sense. Wake up and listen to what Father places in all of our hearts, not to man made non-sense.
- Q: I have an electrical equipment(Its quite old. aybe about 25 years old)These are the ratings:Input : AC 120 V 60 HzOutput : DC9V - 850mAI live in SIngapore which has a power input of 240VMy step down transformer/converter specsMaximum power it can convert is 230 watts
- Your existing transformer/converter will work just fine. Even if it's only 25% efficient your adapter will be pulling just 36 watts. Your transformer is good for over six times that. So you're ok. You want the transformer to have a capacity of at least 20% over the actual load, but more capacity is perfectly ok. Of course, you could also replace your power adapter with one that takes 240V input. That would be a lot more convenient. In the US such adapters normally cost less than 10 USD.
- Q: I just don't understand it, what does it mean when people say 3 phase or 2 phase Voltage, I know higher phases are used to power bigger more voltage demanding things but what does it mean?Can you get both AC and DC in each phase?Is phase just basically saying higher phase higher voltage for higher voltage equipment?How do you convert between phases?Are high phases created with the use of transformers or can they be created directly from things like wind turbines?What is the maximum and minimum phase?How does the phase effect the amps?
- First off you need to realize that AC power is 60 cycle sine wave that goes from positive to negative. (50hz in europe). With 3 phase power you have 3 hot circuits. The peak voltage happen at a different time on each of the 3 hot circuits. You can not have any phases in DC power because DC is a constant voltage, it does not cycle from positive to negative. Higher phase does not higher voltage. You term high phase makes no sense. It's either a 3 phase circuit or a single phase circuit. A single phase circuit is when you have just one hot wire. Like your wall outlet. Note that you can get a single phase circuit by just using one part of a 3 phase circuit. Phase does not affects amps. To make a 3 phase circuit from a single phase circuit you need a motor/generator.
- Q: If an electrical equipment is designed for 220V at 60Hz, can it be used in a country which uses an electrical system of 240V at 50Hz. I'm not sure how true is this, but I've heard that the voltage would not be a problem but if the frequency is less, electrical equipments with motors will not be able to run at 100% performance which means the efficiency drops. Please enlighten me~Thank you
